What exactly is a “domain name system” and why should you care?

What is DNS? DNS is a decentralized and hierarchical naming scheme for computers, services, and other resources associated with a private network or the Internet. It associate different information with different domain names assigned to every of the involved entities.

A DNS server is responsible for maintaining the records associated with domain names and maintains connections between these records. An IP (Internet Protocol) address is a unique number assigned to a computer system and uniquely identifies its owner. There are many types of records used in DNS and the master DNS records contain information about a zone-specific query and lookup requests, while zones are logical labels for domain names and contain zone-wide search queries and records. There are also application records, which define application names and functions for DNS clients and servers. Many vendors provide core networking services that help organizations manage their DNS services, including Infoblox, BlueCat Networks, and Microsoft.

DNS is commonly used in conjunction with nameservers. Nameservers are online reference databases that contain a list of IP addresses, or Internet Protocol addresses (IPs). A DNS server is responsible for translating domain names into IP addresses and then translates the IP address back to a name. A DNS client uses this DNS server's information to find a specific entity on the Internet and then queries the DNS server to obtain the details regarding that entity. When a DNS server successfully returns a match, the client is matched with that entity and is able to access the resource record for that entity. DNS servers store the information in zone files and allow queries to be sent to them by clients.

Records in the DNS database are classified according to their types: authoritative, non-authoritative, and historical context. Within the DNS database, there exists two types of records: zone-wide and zone-bound. Zone-wide refers to the zone of which the domain name is a part, while zone-bound refers to the zones within that zone which have been explicitly added or modified. Zone-wide records are used to create DNS entities while zone-bound records are used to determine how to resolve domain names to IP addresses. Most DNS servers maintain a copy of all zone-wide records in their repository, while some operate internally for zone-bound records only.

Resource records are information that identifies a specific domain name. DNS servers maintain a copy of every data file associated with the domain names that are in their database. These data files include such elements as names, numeric IP addresses, description lines, and other meta-data. The information in these data files enables clients to locate a particular entity from the directory by sending a request for that entity.

DNS resolvers are computer programs that translate query messages into data that can be accessed by clients. The computer program then updates the DNS database by adding or modifying DNS resource records that correspond to messages it has heard. DNS server operators maintain DNS records using DNS resolver databases. These databases are updated periodically and clients do not need to contact the nameservers directly to ask for information about DNS records. DNS queries are sent to the nameservers through an agent which maintains a cache of such queries on its system and responds to those requests from clients with data files that contain answers to the DNS query.

The world is paying the heavy price due to the corona outbreak and subsequent lockdown. But let’s not allow the hackers to penetrate our computer network. It is better to meet a problem in time than to seek remedy after the damage is done. We need to have a powerful security system for connected devices. 

It is a must to ensure our work tools are set up with the proper security. Our computer, phone and tablets should be up-to-date and protected against security threats.  We are very keen in concentrating the DNS level security that plays a key role in the cyber kill chain – 91% of malware use DNS services to build attacks. A global 2019 DNS Security survey conducted by IDC revealed that 82% of respondents said they had been targeted by a DNS attack in the last 12 months. Traditional security systems are not enough to mitigate this type of threat, as they could be easily avoided. 

Dima Business Solutions, Coimbatore-based startup IT Company, has developed a powerful security solution that works seamlessly across devices, which is named “DIMA Warrior”.
